Letters Patent No. 109,630, dated November 29,1870.

The Schedule referred to in these Letters Patent and making part of the same.

I, JACOB M. KEEN, oi the city and county of Phi n'delphia, and State of Pennsylvania, have invented a new and improved Machine for Scoring, Cutting, Cornering, and Blocking oli' Material for Papcr-Boxes, of which the following is a. specification.

The.object of my invention is to combine in one machine all the features that are necessary for preparing pasteboard for making paper-boxes-that is,

scoring, cutting, cornering, and blocking of the material at one operation, thus leaving Iit in aproper state'to be folded and pasted together, to form a com:

'plete box.

Themachine consists of a series ,of rotary scoring and cutting-knives, mounted on shafts which work in appropriate bearings formed in the frames of the machine. The scoring-knives make a longitudinal line of sntficicnt depth (at a certain distance apart, according to the width of box required) to allow the n'iaterial to. be turned up to form the sides'of the box, while the cutting-knives are adjusted so as to cutthe material for the proper height of. the box.

At the back part of the machine, and extending across the same, is arranged-a vertically-moving frame, carrying with it a cutting and two scoring-knives, which cut the material of the proper length, and scores it across for the ends of each box, at the same time a series of rectangular-shaped knives, attached to and moving with the frame, removes square pieces from the corners.

The invention is fully illustrated-in the accompanying drawing, in which- Figure 1 is a side elevation of the machine.

Figure 2: is a plan of same.

Figure 3 is a vertical'transverse section through the center of the machine.

Figure 4 is a detached and vertical view of the sliding frame with its scoring and cutting-knives.

Figure 5 is a bottom plan of same.

Figure 6 is a plan view of the bed on which the knives operate for cutting the corners of the material.

' Figure 7 is a sectional view of the same on theliue At the front part of the frames A and A of the machine are placed two rollers or calenders,B and B, the journals. of which turn in slots formed in the frames. p Immediately back of these rollers are placed two shafts, 0 and 0; one raised above the other, the lower one, 0, being provided witha series of adjustable ollars, D, fig. 3, the set-screw for securing them in position fit in a slot, a, made -in a longitudinal direction on the face of the shaft.

The upper shaft, 0, is provided with a series of scoring-knives, E, which are made circular in form,

and are adjusted on the shaft, similar to the collars same; The knivesdo not cut entirely through th'c v purpose, being made slightly tapering.

The boxes F F, inwhich the journals or the shaft 0 and Q revolve, are fitted in rectangular-shaped recesses made in the frames A and 'A of the machine, and between each of the-upper and lower boxes is placed a rubber spring, Gr, which-forms a yielding bed forthe shaft 0. The boxes, carrying with them the shaft (J, are depressed by means of the set-screws H H, which causes thc.knives E to. bear on the material, and to score ittoa greater onless depth, as required.

Secured to the inner .sides of the frames A and A, at a short distance hack of the shafts 0 and 0, is a bow-shaped frame, I which projects a certain height above the frames, and curves down to within a short distance of the bottom of the same, and acts in the capacity of a brace, to resist the vibrations of the operating parts, and, at the same time, serve as a support for two brackets, J and J, carrying two frictionrollers, 71 b and 7/1).

These brackets give additional stiffness to the shafts, and prevent any undue bending or twisting of them. The rollers on the bracket J revolve in close contact with one of the collars D, while those on the bracket J are kept'in contact with one of the collars on the upper shaft (3. I

The brackets are attached to the fram'el by means of bolts (fig.'3,) passing through-slots formed in it, thus allowing 'them to be moved sideways, in conformit-y with the collars.

They are also supplied with set-crews, H and H, v

for raising and depressing them.

The knives K K, for cutting the paper, are secured to collar L L, which are placed over and are adj usted on the shafts O and 0 similar tothose on shaft 0 and C, the cutting-edges of the said knives lap over and work close together in the same manner as a pair of shears, and cut the material of the proper width after, it leaves the scoring-knives.

The shafts O and 0 are made with an increased diameter, in order to give additional strength to them, and are arranged in the frames A and A similar to the shafts G and G, with a gum spring, G, placed between the boxes F and F.

This portion of the machine, arranged as above described, is for scoring the material in a longitudinal direction, for the sides of the box, and for cutting it of the proper width and height, after which it passes to that portion of the machine hereinafter described, when, by a reciprocating movement of the scoring-and, cutting-knives, the material is marked off for the ends, of the box, cut of the 'proper' length, and the com'rs l), with their outer circumferencesin contact with the removed. a

p the blade of same.

movement in the standards N and N at the rear por- -tion.of the machine, is supplied, at the lower part,

with a. cutting-knife O, and two scoring-knives, 1 and 1", and receives its motion from theside 'rods R and It, (fig. 2,) 'the lower ends of which are, connected to two wheels, S and S, the attachment being made by two crank-pins, which are fitted in slots formed'iu one of the arms of each wheel. 7

The cutting-knife O (figs. 3 and 5) hasits ends fasterred securely to .two cross-pieces, '1- and T, bolted to the inner side of the upright. of the frame, andon each. side of it are placed the scoring-knives P and P. These are also secured-to the under-side of the cross-pieces by means of plates, provided with slots and set-screws,.thns allowing them to be moved closer together or separated. H

The rectangular-shaped knives U 'U, which cut the corner openings'of the boxes, are attached to the-in ner sides of the scoring-knives by means of screws 17. 11, passed through slots formed longitudinal through The score-knives have resting on theirupper edges, and at a certain distance apart aseriesofhead-bloeks, V V, which are depressed, when it is desired that the knives should score aline of increased-depth, by means of the screw-rods V \V, which-pass through the crossbraces X X 'of' the frame. This arrangement also gives additional stiffness, and prevents the knives from springing.

The bed-flame, (figs. 6 and 7,)whiel1 is placed directly under the frame M, is composed of two longitudinal pieces Y Y, provided with gi'OOJQS on the in uer side, in which'areinserted transverse pieces a c c, the whole being securely held together by means of bolts f f. I p

In the center of the bed-frames is secured a wooden strip, 9, provided with,a groove on the upper surface for the reception of the cutting-edge of the .knife 0.

The transverse pieces 0:0 e. of the bed-flame maybe nio'v'cd in a longitudinal directionjn the grooves of'the pieces 1 Y in order to increase or diminish the dis: tance between them, to accommodate different sizes of boxes; or they may be removed and shorter ones substituted, and the pieces 1" and Y drawn closer together by the rods ff.

The ends of the pieces 1 and Y are fitted into guides formed on'the inner side of? the frames A and A, and the under side of the bed-frame is provided with gauges, h h, for regulating and holding it in position when adjusted.

The slots formed in the'whe'els S and S for thereception of the crank-pins ot' the side rods R and 1;, permit of any length of ,stroke beingggiven to the frame M, in order toprodnce a fast or slow-motion of it, thus causing the knife 0, in operating on thema' terial, to ent il: of any length required for the box.

The pastcboard selected for the boxes is passed be-.

tween the rollers B and'B, (fig. 3,) an d in passing uu-' der thescoring-lmives E it receives a series of parallelscoi'-marks in alougitudinal direction, (the knives having previously been set to'snit the width oFbox' required,)-after which it is projected u'mlertheicuttiug knife K, which cut-s thematerial at a certain dista-ncc' from the score-marks, to form, when turned up at ,right angles, the sides of the box."

The material having been out into strips of the properwidth, and being still in motion, is carried-t0- -\vard'the bed 1' Y, under the frame M, and, on reaching the cutting-knife 0, which descends at the proper moment, the ends are cut sqnareand even, at the same time the scoring-knife 1" has marked each piece transversely, to form the ends of the box, while the rcetangular-sha-pcd knivesU U have passed down into the spaces between the pieces 0 c c of the bed and It).

moved square pieces from the material for the corner openings of the box.

The frame M isadjustcd so that, bythe time it has" made a complete stroke, the material has passed andera. suflicient distance for the length of thebox, when the knife O-cnts it, and the knife 1 scores itacross for the opposite ends of the box, while the ad jacent kni'ves, U l remove square pieces for the' corners.

The lids or covers of the boxes are formed in the. same manner, the cutting-knives being adjusted to cut thematerial of a proper size for the depth. 1 claim as my invention- 1.
